Kai's verdictS-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier for designer-led sites. S-tier if animations matter.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.
